A dirt ejector...ejects dirt when you empty the vacuum, so you don’t have to touch it.

A five year warranty

The thing’s a behemoth, and it’s still not cheap, but it’s one of the most powerful vacuums Dyson makes, and it legitimately normally sells for $500. In fact, prior to this sale, the best price Amazon’s previously offered on it was $425, so we’re talking about a pretty massive discount. Just be sure to get yours before they’re all cleaned out.
